Lego GBC Ball Batch Module

This lego great ball contraption (GBC) module features a mechanism that waits for enough balls to be in the mechanism, then it lifts the balls to the next module. I built this module because I wanted it to be easier for people to get into building GBC modules, as it can be quite hard to build your first one by yourself. While it is quite a complicated module, it is still a really reliable module, and it can hold the GBC standard of 30 balls at one time. Hope you like it! You can watch it running here:
